The article presents the results of studying the numbers of alfalfa changeable in the nursery of competitive variety trials (2016-2018) for a set of economically valuable traits. Revealed high winter hardiness of all varieties. On average, over three years in the nursery of competitive variety trials, seed yields significantly exceeded the number standard: Victoria – by 25%, SGP-1 – by 39%, SGP-2 – 93%, 193-95d – by 61%. During the three years of testing, all the indicated prospective numbers were significantly higher in seed yield, the Sarga variety (standard), which indicates a high adaptive mechanism of the studied populations. On average, over three years, the yield of green mass was 28,2-32,8 t/ha, the excess over the standard 3,4-16,3%. The collection of dry matter was 5,31-6,86 t/ha (standard 5.82 t/ha) exceeding 4,8-17,8%, according to this indicator the following numbers should be highlighted: SGP – 2, 193-95д, Victoria. The collection of protein in the third year of use for the season amounted to 1152-1605 kg/ha. Significant excess over the standard (1153 kg/ha) was provided by the following numbers: Victoria – 1605 kg/ha (+39,2%), SGP-1 – 1302 kg/ha (+12,9%), 193-95d – 1505 kg/ha (30,5%), 197-06 – 1388 kg/ha (20,4%). According to the complex of economically valuable traits (winter-hardiness, high yield of fodder mass and seeds, protein collection per hectare), 3 promising numbers were identified - SGP -1, SGP -2, 193-95d.
